NEW YORK —Combate Americas today announced that the scheduled flyweight (125 pounds) showdown between six-division world boxing champion Amanda “The Real Deal” Serrano (0-0-1), and former Mexican national kickboxing champion Erendira “Aketzaly” Ordoñez (2-1), has been elevated to main event status for the Mixed Martial Arts (MMA) extravaganza at the AVA Amphitheater at Casino Del Sol in Tucson, Ariz., USA on Saturday, Oct. 13.

The previously announced bantamweight (135 pounds) main event between Erik “Goyito” Perez of Monterrey, Nuevo Leon, Mexico and John “Sexi Mexi” Castaneda of Mankato, Minn., USA, has been postponed due to a staph infection suffered by Castaneda.

The stacked, nine-bout Combate Americas event streams live in its entirety in English in the U.S. and Canada on DAZN (10 p.m. ET/7 p.m. PT), and the three-bout main card airs live on television in Spanish on both Univision (12 a.m. ET/PT) and Univision Deportes Network (UDN) (12 a.m. ET/9 p.m. PT).

Born in Carolina, Puerto Rico and fighting out of Brooklyn, N.Y. the 29-year-old Serrano will make her second-career MMA star on the heels of her latest feat in the boxing ring – capturing the World Boxing Organization (WBO) Junior Welterweight Championship with a unanimous decision win over Yamila Esther Reynoso of Argentina on September 8.

In doing so, Serrano joined Manny Pacquiao and Oscar De La Hoya as the only boxers in history to capture six world titles in six different weight classes.

The 22-year-old Ordoñez of Mexico City is a three-time San Shou-style kickboxing gold medalist, who holds a professional kickboxing record of 2-2, in addition to her MMA experience.
